Kuisheidsslaaf likt bull's sperma van mijn voeten training

I offered my slave a deal: he can masturbate and cum on my soles, if and only if he first licks my bull's cum off my feet. I love having him on his knees ready to do everything to be able to cum. Of course, after he came on my sexy wrinkled soles, I made him clean up my feet once again !
